Optima lenses for 3 months. Price, reviews

Optima contact lenses, produced by the American company Bausch & Lomb, are used to improve visual acuity. Models are designed for long-term wear - for a period of 3 months. The installed binocular system is comfortable in everyday use and affordable.

Specifications

Optima lenses are made of a special hydrogel material "Polimacon A". The mild formulation contains 62% ethylene glycol in the form of dimethacrylate and 38% aqueous distillate. In terms of chemical structure, Type A Polimacon is a hydrophilic polymer.

The composition has a high oxygen permeability index. The hydrogel provides sufficient moisture to the mucous membrane of the orbit, which allows for a long time not to remove contact lenses. The material does not prevent atmospheric oxygen from entering biological tissues.

Optima lenses for 3 months are available with a base curvature of 9.0, 8.7 or 8.4 mm, which allows for an ophthalmologist to select a model in exact accordance with the individual anatomical curvature of the corneal shell. The binocular system is presented in the optical range + 4.0... -9.0 diopters.

Quarter lenses have a spherical surface. A separate model is intended for the correction of myopia. Optima lenses are presented in several options, differing in purpose and technical characteristics. The models available on the market are shown in the table.

Composition and equipment

The American manufacturer supplies optical devices in hermetically sealed blisters made of aluminum foil and transparent medical grade polymer. Secondary packaging is a box made of thick cardboard.

Each pack contains 4 blister packs containing one contact lens in sterile saline with isotonic properties.

The hydrogel composition from which the binocular system is made is resistant to:

• mechanical damage;
• fracture loads;
• protein deposits;
• exposure to chemically aggressive environments.

The American company manufactures optical devices intended for quarterly wearing using injection molding technology under precisely calculated pressure. Some varieties are formed by a combined method of a reverse process of the III degree.

This method makes it possible to give lenses high mechanical strength, stable technical parameters, and protection against dehydration. It provides for the manufacture of the inner surface of the optical matrix by high-precision laser turning, the outer part - by the method of compression polymerization.

Advantages and disadvantages

Ultra-thin lens edges allow easy installation without corneal irritation. The device does not injure the mucous membrane. The absolutely smooth lens surface fits perfectly on the cornea.

Contact means of visual correction of American production have high optical characteristics.

The advantages of ophthalmic products include:

• The optimum ratio of price and quality;
• mechanical strength;
• high oxygen permeability;
• effective moisturizing;
• the possibility of continuous use for 3 months;
• ensuring high definition of central and lateral visual perception;
• the presence of ultraviolet filters in certain models;
• comfort and safety of everyday use, subject to the rules of operation and maintenance.

Optima lenses, which are enough for 3 months with constant wearing, are not without drawbacks. They are designed primarily for day wear. At night, it is advisable to remove them to exclude the hypoxic state of the cornea, hyperemia of the mucous membrane, and other unpleasant manifestations.

Due to their increased strength, such contact lenses require a longer adaptation to the biological visual apparatus than models with a short wearing period.

The disadvantages of ophthalmic products include the need for specific care and the ability to induce the sensation of a foreign body in the eyes during the adaptation period.

Indications for wearing

Quarter contact lenses are designed to correct visual acuity in patients without severe ophthalmic pathologies, with minimally pronounced astigmatism and other similar disorders.

Special medical indications for the use of American-made binocular products:

• Myopia. A state of myopia caused by the focusing of light radiation in front of the retina. The pathology is characterized by the elongation of the eyeball.
• Hypermetropia. Visual impairment is called farsightedness. Unlike myopia, in hyperopia, light entering the retina passes through the lens and is focused behind the membrane.
• Astigmatism. Refractive disruption provokes a change in the geometric configuration of the cornea or ocular lens, leading to the scattering of light radiation and the formation of a distorted (bifurcated) Images. Optima contact lenses are designed to correct minor astigmatic disorders.
• Amblyopia. Persistent deterioration of visual perception in one or both eyes, not associated with organic damage to the optical analyzer and not amenable to drug correction.
• Lack of lens body. Such a defect is caused by hereditary causes, traumatic injuries, cataract removal.

The binocular quarterly system is used for diseases of the cornea or conjunctival membrane. Optima lenses are indicated for the correction of occupational disorders in medical workers, athletes, and builders.

Contraindications

It is forbidden to use such ophthalmic products in case of allergic reactions to the components of the hydrogel composition.

Patients with:

• an inflamed eye condition;
• infectious lesion of the structure of the optical analyzer or adjacent tissues of the periorbital zone;
• seasonal flu;
• colds;
• impaired structure or functionality of the lacrimal glands.

Optima lenses, designed for continuous wear for 3 months, cannot be used in dry air, dusty atmosphere, chemically aggressive vapors.

Ophthalmic devices are not prescribed for the following inflammatory eye diseases:

• blepharitis;
• conjunctivitis;
• dacryocystitis;
• uveitis;
• sclerate;
• keratitis;
• iridocyclitis.

It is forbidden to install the binocular system to patients with lens subluxation, ptosis century, an altered pathological process or bacterial damage to the chemical composition of the lacrimal liquids.

It is recommended to refrain from using contact lenses while taking diuretic, antihistamines, vasoconstrictor drugs. The use of ophthalmic products is contraindicated in systemic pathologies - diabetes mellitus, tuberculosis, asthma.

Instructions for use

Optima contact lenses are designed for daily wear. You can use ophthalmic devices for a maximum of 10-12 hours. contract.

Exceeding the established operating limit leads to:

• drying out of the mucous membrane of the visual analyzer;
• burning sensation in the eye sockets;
• inflammation of the conjunctiva;
• other undesirable effects, side effects and discomfort.

Ultra-thin products are easy to install but take some getting used to. Patients without experience with such medical products are faced with turning optical discs inside out.

To eliminate installation errors, the manufacturer has marked the front side of the quarter lenses with a clearly visible designation. If the recommended storage rules are violated, products tend to stick together.

To disconnect ultra-thin optical discs, they are placed for 3-5 minutes. in isotonic solution. In a neutral liquid medium, products restore their original shape during mechanical deformation.

How to put on and take off your lenses

The installation procedure is performed with thoroughly washed and dried hands.

Step-by-step installation algorithm:

1. Open the individual packaging with a contact lens.
2. Place the ophthalmic product on the back of the end phalanx of the index finger.
3. Pull the eyelid off with your free hand, looking up.
4. Place the lens under the border of the pupil, face out.
5. Release the eyelid and perform a few blinking movements or gently massage the skin of the lower edge of the periorbital zone.

In case of differences in the visual ability of both eyes, it is important not to confuse the diopters. Each package with a lens has a mark on the optical power inside the product. To remove the ophthalmic device, pull the lower eyelid, blink quickly, or lightly touch the edge of the disc.

Care rules

A fresh solution is used for each sanitary-antiseptic treatment of quarter lenses. With increased sensitivity of the visual analyzer and the surrounding skin, a compatible composition should be selected that will not cause an allergic reaction or irritation.

The optical disc storage container is washed and dried daily. After removing ophthalmic products from the eyes, each time they are poured with a fresh solution. Isotonic fluid cannot be reused.

Specialized containers for storing lenses are changed every month. The old containers are disposed of in accordance with the rules established for medical devices.

Always have a new container for urgent removal of lenses from the eyes within easy reach. Expired optical discs must not be used. Such products can cause serious consequences and worsen visual dysfunction.

Terms of use

Optima lenses, which will last for 3 months with constant use, cannot be worn longer than the specified period. After 90 days, they must be replaced with new ones. The operating period established by the manufacturer must be strictly observed. After this time, optical discs lose their corrective effectiveness and can cause deterioration in visual function.

Special conditions of use

To clean contact lenses, use specialized isotonic solutions. Aosept plus and Bio true are compatible with Optima ophthalmic products. To remove protein and lipid deposits, dissolving tablets with enzymes that break down such compounds are used.

If other substances are used, there is a risk of damage to the optical discs, cloudiness or additional surface contamination. It is not recommended to swim in the sea water, use the swimming pool or solarium with the lenses installed.

It is necessary to avoid contact with the surface of products of aggressive chemical substances and vapors. If the rules for sanitizing and using contact lenses are violated, the eyes may become infected with pathogenic bacteria, the development of limbal keratitis or papillary conjunctivitis.

Makeup

American-made ophthalmic products are compatible with cosmetics. It is undesirable to spray the hair-fixing varnish with the quarter lenses installed. It is recommended to style your hair first and then install the optical discs.

It is necessary to avoid contact with the eyes of alkaline compounds contained in hygiene products - toilet soap, shampoo, shower gel. Microparticles of mascara, foundation and other types of decorative cosmetics can contaminate the surface of lenses and impair their optical properties.

It is recommended to wear contact lenses before applying makeup. Rinse off decorative cosmetics after removing the ophthalmic devices from the eye sockets. It is advisable to choose makeup products on a water basis while wearing contact lenses.

Such substances, even when they hit the surface of the disc, do not leave greasy, difficult to remove stains. Oil cosmetics can damage lenses, which negatively affect their transparency and destroy the structure of the hydrophilic polymer.

It is recommended to give preference to shadows, powder or blush of a creamy consistency. Fine particles of cosmetics will inevitably settle on the surface of contact lenses. Cream substances are safer for optics, adhere better to the skin, effectively moisturize the epidermis.

It is advisable to choose mascara that does not spread and does not crumble. For combination with contact lenses, it is recommended to use waterproof cosmetics. There are special makeup products that have undergone comprehensive ophthalmological testing.

Eye drops

In case of pathological dryness of the mucous membrane of the visual analyzer, it is necessary to use moisturizers before installing contact lenses. Fake tear drops or lubricants will do. These medications additionally clean the surface of the optical discs.

You should choose drops without preservatives, which tend to accumulate on the surface of the lenses and cloud vision.

Combine with optical discs:

• Artelac saturated with hyaluronic acid;
• Systane Ultra is an effective tear substitute based on natural polysaccharide;
• Gilan is a preparation with moisturizing and anti-inflammatory properties;
• Hilo-chest of drawers - German eye drops that provide long-lasting hydration and increase the comfort of wearing contact lenses.

It is better to entrust the selection of a compatible liquid medicine to an ophthalmologist, who will take into account the clinical picture and the state of the visual analyzer. Compatible eye drops can help prevent tear damage and chronic corneal dryness.

Optima lenses cost for 3 months

The price depends on the number of products in the package, the model of ophthalmic devices. The estimated cost of a pack of 4 American Optima FW lenses, designed for use for a period of 3 months, is 990 rubles.
